It's claimed that John DeLorean originally had wanted the system to open the mufflers, advance the timing, and open the Ram Air flaps, but the production item was nowhere near as complicated.
The VOE was made famous by this GTO commercial that ran during the Super Bowl.
Supposedly, the option was only available with the standard 400/350 motor and possibly the optional 455/360; none of the Ram Air motors were available with VOE due to the radical cam and, hence, lack of vacuum.
In the commercial, you can see the bracket is also shared with the Ram Air cable, but chances are this car (which also appeared in the dealer brochure) was a cobbled-up pre-production vehicle. All told, 212 hardtops and 21 convertibles were built with this option before it was cancelled in February.
the advertising for this was enough to get people interested, but GM killed it fast.

Wonder if I could fit something like this to my '69 Firebird? Nah.
ReplyDeleteyou ought to if you can afford it, or turn in your man card! If you can't afford it, I can understand it, I can't afford some cut outs right now either. But when I can I'm getting the pushbutton operated kind. I installed wingnut plates on my last beast. Cool, and not too long to change out, but... a little darn hot on the fingers!

ReplyDeleteI bought one of the 212 Hardtop GTO's in 1970 with the VOE system. Because I live in Minnesota and have put 140,000 mile on this car I am now trying to build a new set of mufflers with this cut out system on it.
ReplyDeletei had a convertible with the system. unfortunately it burned up in my garage. i still have the under dash valve/switch.
ReplyDeleteThey pulled the VoE from the market by the end of February 1970. They didn't offer the 455 in the G.T.O. Judge until the 4Q 1970, so no 455 H.O. ever had VoE from the factory.
